Creative Cloud Packager fails to download

With the recent release of the 2018 version of the Creative Cloud suite, I was looking to create a new installation package with Creative Cloud Packager. All looks like it's going well, I select all of my options and tell it to start building the package.

When it gets to the point of downloading Lightroom Classic CC, it stops immediately and goes back to the list of applications to include in the package. Lightroom CC Classic now has a yellow triangle with a '!' in it next to it. Mousing over it, all it says is "Oops something has gone wrong, please try again."

I've tried purging the cache, as well as going into the cache folder and manually deleting everything from that folder. I've also tried pointing the cache folder to a different location to shorten the path. So far, nothing has worked. Strangely enough, after purging the cache, it still shows a number of the applications as partially, or fully, downloaded. I would've thought that would wipe out all of that. I've tried to go hunting for where those partial/complete downloads might be, but haven't had any luck so far.

That happens when I'm trying to build a package for Windows. I was able to build a 2018 package for the Macs without any issues.

Does anyone have any suggestions on what to try next?

Thank you!
